To all whom it may concern:

Be it known that I, Hans KRInosMANN, merchant, subject of the King ofSaxony, residing at 10 \Vurzenerstrasse, Leipzig-Anger, Germany, haveinvented new and useful Improvements in Machines for ArtificiallyLengthening the Barbs of Ornamental Feathers, of which the following isa specification.

The present invention relates to a machine for lengthening the barbs ofornamental feathers, as for instance ostrich feathers by connectingothers to them with a view to enhancing their decorative appearance.

The machine is adapted to do the work previously done by hand, which isextremely laborious and difiicult owing to the delicate material, and todo it more rapidly and uniformly by curling the barbs of the feathersinto loops which are then pulled into a knot by hand.

The machine is illustrated in the accompanying drawings in which Figure1 is a side view, and Fig. 2 a plan. Fig. 3 shows the driving mechanism.Fig. 4t is a front view, showing especially the mechanism for formingthe loop. Figs. 5 and 6 show details of the latter, partly in section.Fig. 7 is a side view similar to Fig. 1 with the actuating device inworking position. Figs. 8 to 11 illustrate various positions of theloop-forming device, and Figs. 12 and 13 show the loop and the tied knotrespectively.

Arranged on a base plate 1, having a slot 2, is a slide 6 movablebetween guides 3, 4: and acted on by the spring 5; this slide isconnected to a driving cord 8 running over a pulley 7. The slide 6 (Fig.3) has at its front end a movable lever 9 projecting through the slot inthe base plate, and it is provided centrally with a stepped rack 10 andcarries at its rear end a wiper 11 and a bearing block 12 to which issecured a pivoted lever 13 and a striker 1 1. A stop 15 having a paddedsurface is provided at both ends of the base plate 1 for the purpose oflimiting the movement of the slide (5.

The loop by means of which the two feather barbs are knotted together isformed by the rotatable and vertically moving hollow body 16 with whichis connected a clamp 17 which with the aid of the clamping device 18,opposite the cylinder 16, is adapted to hold the barbs while the loop isbeing formed. The hollow body 16 (see Fig. 5) is arranged on a hollowshaft 19 fixed to the base plate 1. At the top said body 16 is a helmetshaped head provided with a longitudinal slot 20, (Figs. 8 to 11) andkeyed to its lower end is a toothed wheel 22 which is adapted to berotated by the stepped rack 10 on the slide 6. At a suitable distanceabove this toothed wheel is a cup shaped disk 23 which serves to liftthe cylinder 16 by acting as a tappet for the bent lever 25 secured tothe bearing block 24 on the base plate 1 (see Figs. 1 and 7), said lever25 being actuated by the lever 13 when the slide 6 moves forward. Aspring 26 engages the disk 23 and is provided with a boss at its freeend adapted to engage a depression in the disk 23 when the cylinder 16is in its raised position, whereby the cylinder is prevented fromturning back. The clamp 17 at the side of the hollow body is aspring-actuated bell-crank lever, the lower arm 27 of which has aninclined surface adapted to be engaged by the wiper 14 on the slide 6.Inside the hollow shaft 19 is a reciprocating pin 28 which carries, atthe end passing through the base plate 1, a projection 29 which isengaged by the slanting spring actuated lever 30, the upper part ofwhich is pivoted near the base plate 1 to the plate 31. The pin 28 isoperated by the lever 9 striking the lever 30 when the slide 6 is inmotion (Fig. 7 The holding device 18 (Figs. 41 andG) comprises a clampwith spring-pressed arms 32, 33. The first of these arms is connectedwith a movable lever 35 which is influenced by the spring 3 1-. Thislever projects through the plate 1 and is pivoted to a plate 36. Theother arm 33 is angular and carries at its lower end a roller 37 whichis adapted, by running on the wiper 11, to open the clamp and therebyrelease the barbs of the feather. The feathers which are to belengthened can be held during the looping process by a suitable holdingdevice fitted upon the machine, which is not shown on the drawing. Theloops, by means of which the barbs are tied together, are formed in thefollowing manner. The two ends of the barbs a and Z) to be tied togetherare on the one hand clamped in the clamp 18 and on the other hand in theclamp 17 secured to the cylinder 16 (see Figs. 1 and 8). Then the cord 8is pulled in the direction of the arrow by means of a pedal, not shownin the drawings whereby the slide 6 is moved forward 1 between the guidebars 3 and 1. During this movement the first step of the rack 10 engagesthe pinion 22 on the cylinder 16, this causing the latter to rotatearound the hollow shaft 19. This rotation causes the clamped featherbarbs to curl around the thinnest part of the cap 21, whereby the clamp18 is pulled toward the cylinder 16 (see Fig. 9). The lever 13 on theslide 6 having participated in the movement of the latter moves fartherforward and striking the curved lever 25 presses it against the disk 28in the cylinder, whereby the latter is lifted (see Figs. 7 and 4). Asthe cylinder is further rotated by the second step of the rack 10, thenext turn in the barb is placed in the recess underneath the cap 21 (seeFigs. 5 and 10). The last teeth of the rack have now passed beyond thepinion 22 and the cylinder 16 is held fast by the spring 26 (see Figs. 1and 3) which always rests on the disk 23. As the slide 6 continues tomove forward in the direction indicated by the arrow the lever 9 (seeFig. 7) and the wiper 11 which are also secured to the slide 6 now comeinto operation. The lever 9 strikes the rear part of the springinfluenced lever 30 and pressing the latter upward also raises the pin28, sliding vertically in the hollow shaft 19 (see Figs. 5 and 7). Asthe pin 28 rises it pushes up the ends of the barbs which lie in therecess underneath the cap 21 (see Fig. 11) and are released at thismoment by the clamp 18 owing to the roller 37 on the arm 83 running onthe surface 11. The operator attending the machine takes hold of theseends a and 6 (see Fig. 12) and in pulling them away knots the loopformed thereby (see Fig. 18). The ends of the barbs which have beenpushed up by the pin 28 are withdrawn from the cap 21 by passing throughthe slot 20. Now the clamp 17 is opened by the wiper 14 on the bearingblock 12 pulling down the horizontal arm 27 of the clamp. If the pedalis now released the slide 6 is pulled back by the spring 5 put undertension in the first instance by the depression of the pedal. Duringthis rearward movement the levers 9 and 18 turn over into their slidingoff position and release the parts adapted to be operated by them. Therack 10 again engages the pinion 22 and turns the cylinder back to itsposition of rest. The plate 11 is simultaneously pulled back fromunderneath the roller 37 and the clamping mechanism is pulled back bythe spring 34 into its original position.

This machine, which may be used anywhere where it is desired to tie theends of barbs together, is fastened on a table. It is covered by a casein such manner that when working only the upper part of the clamp 18 andthe head of the cylinder 16 is visible,

which parts may, however, also be covered when the machine is not inuse.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

1. A machine for tying additional barb lengths to the barbs ofornamental feathers characterized by a rotating and vertically movinghollow cylinder with a head provided on one side with a longitudinalslot, in combination with a pin capable of sliding axially therein.

2.
